Filters descriptions

  • Popular
    1. openICPSR studies
      Replication data and other self-published studies that were previously found on OpenICPSR. Includes studies from these repositories as well as OpenICPSR itself. Some data and documentation have undergone a review by journal staff but OpenICPSR studies have not been curated or checked by ICPSR staff for accuracy or completeness.
    2. Curated
      ICPSR curators describe, check, and document data to facilitate findability and reuse. Most curated studies have files formatted for the common statistical packages.
    3. Exclude Restricted Use
      Selecting this filter returns studies with at least one dataset that is immediately downloadable. Restricted data require an application process that includes obtaining institutional signatures and IRB approval or exemption.
    4. Online Analysis Available
      The SDA online analysis tool can be used to manipulate variables, perform basic and advanced analyses, or subset the data without requiring users to know or access additional statistical software.
  • Recent Releases
    Data that have been added to the ICPSR catalog most recently.
  • Time Period
    The year(s) during which data were collected or to which they refer.
  • Subject Area
    A collection of studies organized around a limited number of common, broad topic areas that are widely represented within ICPSR’s data holdings. Previously referred to as classifications.
  • Subject Terms
    A subject term indicates what the study is about and summarizes its content in order to increase its findability. Subject Terms follow the ICPSR Subject Terms Thesaurus and the Library of Congress Subject Terms.
  • Geography
    The location from which data were collected or to which they refer.
  • Time Method
    A collection of studies that share a key characteristic or connection, such as a shared data producer, format, purpose, method, or project.
  • Group
    A collection of studies can be used together because they include the same or related respondents, questions repeated over time, or related data at different levels of aggregation.
  • Series
    Describes whether a study represents data collected at one or multiple points in time and, if multiple, whether from the same or different respondents.
  • Data Availability
    Indicates whether data are available to anyone (public) or freely available to those at ICPSR member institutions and for a fee to others (members).
  • Investigator Affiliation
    Institutional affiliation of the investigator(s) at the time that they collected and/or deposited the data.
  • Funding Sources
    The sources of funding that supported the data collection.

Badges descriptions

  • Curated
    ICPSR curators document, format, and check data to facilitate findability and reuse.
  • Self-published
    Researchers publish their data and metadata without the assistance of ICPSR staff curators.
  • Restricted
    A study contains data that, due to sensitivity and/or confidentiality, require an application to access.
  • Simple Crosstabs
    Explore combinations of variables in datasets within these studies prior to downloading using a tool that runs unweighted crosstabulation (contingency) tables, allowing for controls. Good for evaluating whether there are enough respondents in key groups to support intended analyses.
  • Self-published
    These data are available from an external resource. ICPSR doesn't archive or store these data for download.
